Approximated division of the circumference of a circle into equal parts by rays from the center

Abstract

Vl. Meyer addressed me with a letter, in which he reported on a graphical method of dividing a circle into equal parts using a simple technique (see article). Of course, theoretically this is not correct; it is impossible even to generally establish the perspective of points on a circle and on any straight line otherwise than by taking the center of the perspective rays on the circle itself. Mr. Meyer's method has no theoretical basis and can only be approximate in relation to the semicircle. This method can really be used at least in construction work, for example, when placing pillars and columns around the circumference of a circle.
